VTo @ZZ whom it may concern.-

Be it known that we, WALLACE S. OLDs and DAVID M. HOUGH, citizens of theUnited States, residing at St. Louis, in the county of Gratiot and Stateof Michigan, have invented certain new and useful Improvements inCarbureters, of which the following is a specification, reference beinghad therein to the accompanying drawings.

The invention has reference to a carbureter particularly designed forwith explosiveengines; and our invention consists in the construction ofa novel device of this character and in the combination of its variousparts, as more fully hereinafter described, and shown in which Figurelis a vertical central section thro ugh a oarbureter embodying ourinvention; and Fig. 2 is a cross-section taken on line a; fr, Fig. 1.

In construction the carbureter comprises an inclosing casing A, having aclosed upper end B and terminating at its lower end in a neck portion C,as plainly shown in Fig. 1. The casing is provided with an air-inletport D in proximity to the neck portion and with an outlet-port E nearits top. y

F designates an outlet-pipe communicating with the interior of thecasing through the port E,through which the mixture passes to the enginein connection with which the carbureter is adapted to be used.

Gr represents the air-inlet pipe, through which air enters thecarbureter through the port D. This pipe may be of any approvedconstruction. Freferably, however, vided Vwith a closed end a and hasformed therein in proximity to said end lateral airinlet ports b.

The neckportion of the carbureter before referred to is formed,preferably, in the following manner: I-I designates a threaded nippleengaging within an aperture I in the lower portion of the casing, and Jrepresents a T-coupling, which has `a threaded engagement with thenipple referred to and is provided with an overllow-pipe K f In the freeend of the T-coupling isarranged a bushing L, which forms a restrictedpassage within the neck,` and M is an elbow having a threaded use inconnection the drawings, in

`.The gasolene or any engagement with the bushing, and O is asupply-pipe communicating with the elbow.

Arranged within the casing is a liquid-discharge device P, which is inthe form of a discharge-pipe Q., the lower` end of which is fittedWithin the plate R, which is preferably conical in configurationandwhich also has formed in its upper face a valve-seat S. y

'T designates a valve adapted to be seated upon the deliector-plate, and`U is an operatL ing-'stem for said valve,which extends through anaperture o' in the casing-top. The stem is threaded, as at d, at itsupper end to engage a corresponding thread in the aperture, and V is anoperating handle or head upon the portion of the stem which projectsbeyond the casingl The operation of the device is as follows: volatileliquid that is found preferable in use passes through the supply-pipe Oto and through the discharging device. The valve is raised from its seatto permit the liquid to pass in a thin film over the conical head ordelector-plate and in a suicient quantity to drop from said plate to thebottom of the casing. The air entering theinlet-port D evaporates thegreater part of the liquid film upon the spreadereplate and also aconsiderable portion of the drops as they pass down through theair-current, and the mixture or vapor is discharged through theoutlet-pipe F to the engine to be used in the ordinary manner. The valveT may be regulated so as to produce the desired flow of liquid throughthe discharge device, and the residue of the liquid which is notdischarged with the air through the outlet-pipe is conducted away fromthe carbureter through the overflow-pipe K.

It will be observed from the construction of our carbureter that meansare employed for spreading the liquid, so that the evaporation of thelatter will be more readily e'ected. It will also be seen that byarranging the parts in such manner that the liquid will drop through theair-currents a still further evap oration of the liquid may be obtained.

What we claim as our invention isV 1. In a carbureter, thc combinationof the bushing L. Upon the top of the discharge-pipe is an apertureddeiiector- ICG mixing-chamber provided with an air inlet and an outletport, a liquid-discharge pipe extending Within the chamber, an aperturedSpreader-plate upon the free end of the d ischarge-pipe havingavalve-seat formed in 1ts upper face, a valve controlling the dischargefrom the pipe, an operating-stern for said v3.1 ve extending through andhaving a threaded engagement with the casing, and an overlowl pipeleading from the casing.

2. In a. carburetor, the combination with an inclosug casing terminatingat its lowerend in a. neck portion and having a closed upper end, thecasing being provided with a.

lateral air-inlet port and a similar outlet-port,- a liquidLsupply pipecommunicating with the interior of the neck portion, a liquid-dischargepipe Within the casing having one end extending within the neckandcommunieating with the supply-pipe, an apertured spreader-plate uponthe free end of the discharge-pipe, said plate having a.' Valve-seatformed in its upper face, a. valve adapted to Seat upon the plate, anoperating-stem for said valve lextending through and having a threadedengagement with the closed upper end ofthe casing, and an oVeriiow-pipeleading from the neck above the supply-pipe, substantially asdescribed.' p

e In testimony whereof we affix our signapuree in presence of tWoWitnesses.
